Set of 12 high performance exhaust valves for the 6 cylinder Honda CBX 1000.

Made of the best grade stainless steel (EV8 / 21-4N) commonly used in all high performance valves used for racing or high strung engines (N/A, turbo or nitrous), these are a great improvement over the standard valves not only in flow but also in strenght and heat resistance.

Valves are finished with durable black nitride coating to avoid stem wear and increase durability. All valves have hardened valve tips.

These valves are 23,5mm.

These valves were designed to work with the original valve seat requiring only  usual valve seat machining.

Oversize valves are a great way of increasing cylinder head flow for modified and big bore engines.

Oversize intake valves and titanium retainers also available
